Answer:

c=−3 or c=7

Step-by-step explanation:

Step 1: Cross-multiply.

c/3= 7/c−4

c*(c−4)=(7)*(3)

c2−4c=21

Step 2: Subtract 21 from both sides.

c2−4c−21=21−21

c2−4c−21=0

Step 3: Factor left side of equation.

(c+3)(c−7)=0

Step 4: Set factors equal to 0.

c+3=0 or c−7=0

c=−3 or c=7

If a sector in a circle of radius 10 has an area of 5π, what is the measure of the central angle that forms the sector?
belka [17]
Area of sector=sectorfraction times area
sector fraction=angle/360

area=pir^2
r=10
area=pi10^2=100pi

so
5pi/100pi=xdeg/360
1/20=x/360
times both sides by 360
18=x
answer is 18 degres

The ordered pairs (0, -2), (1, 1), (2, 4), (3, 7), and (4, 10) represent a function.  What is a rule that represents this functi
fiasKO [112]
I just started doing function in my Algebra class. So what I was taught was there can't be more than 1 output aka "y" for one input aka "x".

So with the ordered pairs you have above is a function because there's only 1 output coming out. I have a picture showing why. It's labeled a purple one. 
You know a graph or anything is not a function because it has more than 1 output which is not okay. For example: (1,6), (5,3), (2,9), and (1, 7) Now you notice that I have two coordinate pairs that have x for 1 and y for 6 and 7. I have another picture showing a example of a non-function.
